I have a hard time understanding who exactly cooking anime appeal to and how cooking became a genre.
Here's a list of cooking anime:
1987, Mister Ajikko
1997, Chuuka Ichiban
2004, Yakitate!! Japan
2008, Seiyou Kottou Yougashiten: Antique
2009, Cookin' Idol Ai! Mai! Main!
2009, Yume-iro Pâtissière
2015, Shokugeki no Souma
2016, Shokugeki no Souma: Ni no Sara
2017, Shokugeki no Souma: San no Sara
2017, Isekai Shokudou
2017, Emiya-san Chi no Kyou no Gohan
2018, Shokugeki no Souma: San no Sara - Tootsuki Ressha-hen
2018, Isekai Izakaya: Koto Aitheria no Izakaya Nobu
2019, Shokugeki no Souma: Shin no Sara
2019, Shin Chuuka Ichiban!
2020, Shokugeki no Souma: Gou no Sara
2021, Shin Chuuka Ichiban!
2021, Isekai Shokudou 2
Shokugeki no Souma alone has already six seasons and they even resurrected the 1997 anime Cuuka Ichiban to get another two seasons in 2019 and 2021.
